To all whom it may concern.-

Be it known that we, WILLIAM S.-TEEPLE- and SAMUEL O. JOHNSON, citizens o'f the' United States of America, residing'at' Wellsburg,in the cou nty of Brooke and State of West Virginia, have inventedoertain new and use-f ful Improvements in Glass-BlowingMachines,- of which the following is a speci-ficationyreference being had therein to theaccompany ing drawings. f 1 4 This inventionrelates to certain new-and useful improvements inf'glass forming and blowing machines, and has for its 'object'the provision of novel means whereby glass is formed in a mold and then blown to the proper shape desired; I i r Our presentinvention further contemplates providing a portable mechanism that may be easily operated by hand and wherein the forming and blowing mechanism may be operated simultaneously; furthermore,to p rovide a ma; chine that will form the glass in amoldand; another mold complete the operation of blow ing it to the proper shape. I Our invention still further aims to provide; a common shaftithat maybe easily and con-; veniently operated by a hand-lever and to; attaohto said shaft such mechanism as will simultaneously lower the plunger into the mold for forming the article and also lower the: blowpipes, having arranged therein check-- valves that will be automatically opened when; lowered to the proper position and admit airpressure into the vessel to be blownto the proper shape. v

The present invention has for its stillfurther object to mount the mechanism uponia portable carriage that may be conveniently placed in one position or another, as desired; furthermore, to provide a mechanism 'thereoni of the above-described character that will be extremely. simple in construction, strong, durable, comparatively inexpensive to manufacture, and highly'efficient in its operation. With the above and other objects in view the invention consists inthe novel combination and arrangementpf'parts, to b'e hereinafter more'fully described, and specifically pointed out in the claims.

In'describing the invention in detail reference is had to the accompanying drawings,

" forming a part of this specification,and where- 'in "like numerals of reference indicate like parts throughout the several views, in which- Figure 1 isa front elevation of our-improved machine. Fig. 2 is an enlarged vertical sec- :tioual view of the'lower endfof one of the blowpipes, showingthe check-valve arranged therein. Rig; 3 is an enlarged side elevation offthe eccentric"securedtoth end of the shaft tooperatetheblowpipes. i

In the drawings the reference-numeral l i-repr esen ts the truckor-carriage; carrying the table 2. Upon the'upper face of this table are :mounted standards 3,-upon which standards 3 is slidingly secured a yoke 4, said yoke 4 ihaving outwardly-extending arms 5 5, to

which are secured pitman-rods 6 7. The'pitman-rod 6 is pivotally secured at 8 to'the'pin 9,th elatter being eccentrically arranged upon the wheel*l0,"thiswheel 10 being mounted upon a shaft 11, which shaft is journaled in bearings 12, 14', and 15, which are rigidly se- "cured or bolted to the under face of the table 2. The pitman rod 7e'Xtendsthrough an opening in the table 2 and is likewise secured to a pinld, eccentrically secured to a wheel 17,'which is likewise mounted upon the same shaft as wheel 10. A screw-threaded shaft 1 8fextendsthroughthe yoke 4 and carries a yoke 19, this yoke being secured in position upon said screw-threaded shaft 18 by means of jam-nuts 20. The said yoke has slidingly securedtherein rods 21, these rods at their upper ends carrying nuts 22 and at their lower .ends are rigidly secured to the-yoke 23. The said rods 2l-areencircled by spiral springs ;24. Thefyoke 23 slidesuponj the standards- A yokei2is slidably secui'ed to the stand- "ardi3, through whic'h extends a plunger 26 and the-screw-threaded shaft 18, the said 'plunge1f26operating into the mold 27. An operating-lever 28, secured' to the outer end of the common shaft 11, :serves the'purpose of operating the mechanismof the plunger or press. This common shaft -11 -carr ies at its other end an eccentric"29,-operating1in a split sleeve 30, carrying flanges 31, which are secured together by bolts 32, the said split sleeve being securedat 33 to the reciprocating shaft 34, extending through the opening .35, formed-in the table 2. This reciprocating shaft 34 extends upwardly through the guide 36, mounted upon standards 37, which are rigidly secured or bolted to the table 2. The reciprocating shaft 34 carries a crosshead 38, in which are secured blowpipes 39, said blowpipes extending upwardly through the guide 36 and carrying at their upper ends couplings 40 to be secured to the flexible airpipes leading from the airpressure tank. (Not shown in the drawings.) In the lower extremity of the blowpipes 39 are arranged check-valves 41, said blowpipes carrying an annular shoulder 42. Upon the lower end of the blowpipes 39 are slidingly secured heads 43, and a spiral spring 44 is secured in said head, encircling the lower end of the blowpipe and abutting against the annular shoulder 42. Air-ports 45 extend through the lowerportion of the head and communicate with the interior air-chamber 46, formed in the head. A buffer-spring 47 also encircles the lower end of the blowpipes, said buffer-springs being interposed between the cross-head 38 and head 43.

The operation of our improved device is as follows: As the operating-lever 28 is lowered or raised movement will be communicated to the Wheels 10 19 and eccentric 29, thereby lowering the plunger 26 and ainpipes 39. It will be noted that by this single movement of the lever one vessel will be formed and at the'same time another one will be blown.

The many advantages obtained by the use of our improved mechanism will be readily apparent from the foregoing description taken in connection with the accompanying drawings.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of our invention.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described, the combination of a table and a pair of standards carried thereby, a yoke slidingly mounted on the standards and carrying outwardlyextending arms with pitmen secured to the arms, a shaft supported on the under side of the table and carrying wheels eccentrically connected to the said pitmen, a screw-threaded shaft extending through the yoke carrying a yoke near its lower portion, a pair of spring-pressed rods slidingly mounted in said last-named yoke, said rods at their lower ends having a yoke rigidly secured thereto slidingly mounted upon the standards, a yoke carried by the lower end of the screw-threaded shaft and movably secured-to the standards, a plunger operating through said last-named yoke, a second pair of standards supported by the table and carrying a guide with a shaft carrying a cross-head operating through the guide, a split sleeve carried by the lower end of the shaft, an eccentric mounted on the firstuamed shaft and engaging in said split sleeve, blowpipes carried by the cross-head and operating through the said guide, substantially as described.

2. In a device of the character described, a table havingapair of standards carried thereby with a guide connecting the standards, a reciprocating shaft operating through the guide and table and carrying a sleeve at its lower end, a shaft supported by the table and carrying an eccentric engaging in said sleeve, a cross-head mounted on the firstnamed shaft and carrying blowpipes operating through the guide, shoulders on the lower ends of the blowpipes, heads slidingly secured on the blowpipes and having air-ports therein, and springs on the blowpipes interposed between the shoulder and the head and the cross-head and the head, substantially as described.

In testimony whereof we aflix our signatures in the presence of two witnesses.
